Upper control arms work in concert with the lower control arms to locate the rear axle throughout its range of suspension travel. Metco’s upper arms feature adjustable length to dial in your pinion angle, a must-have for drag racing, especially when using drag radials or drag slicks. Metco’s arms are precision machined from 6061-T6 billet aluminum, and are double adjustable with a nickel plated adjuster and powder coated clevis. Energy Suspension polyurethane bushings are included; the frame side bushings are pre-installed, while the installer must install the included axle-side bushings. These come pre-assembled to the factory arm length. Grade 8 hardware is included.
Fits 1978 – 1996 GM B-Body including Chevy Impala, Chevy Caprice, Buick Roadmaster, and Cadillac Fleetwood. Fits sedans and wagons.
